How to set some Hibernate properties in Spring JPA Web Application?

Question

I am trying to get rid of the typical persistence.xml file in Spring JPA web application. So far, I have managed to inject the EntityManager successful

Answer 1

Spring provides a way to configure these options in provider-independent way using AbstractJpaVendorAdapter (setDatabase() and setGenerateDdl(), though setGenerateDdl() doesn't take DDL mode).

Alternatively, you can pass arbitrary properties to LocalContainerEntityManagerFactory using setJpaProperties() (or setJpaPropertyMap()):

Properties props = new Properties();
props.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
props.put("hibernate.hbm2ddl.auto", "create");
factoryBean.setJpaProperties(props);

This is the old question but might help someone who is using XML for configuration.

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="test-jpa"/>
    <property name="dataSource" ref="dataSourceProxy"/>
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
    </property>

    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true"/>
            <property name="generateDdl" value="false"/>
            <property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect"/>
            <property name="database" value="MYSQL"/>
        </bean>
    </property>
    <property name="jpaPropertyMap">
        <map>
            <entry key="hibernate.jdbc.batch_size" value="10"/>
            <entry key="hibernate.jdbc.fetch_size" value="10"/>
            <entry key="hibernate.order_inserts" value="true"/>
            <entry key="hibernate.order_updates" value="true"/>
            <entry key="hibernate.jdbc.batch_versioned_data" value="true"/>
            <entry key="hibernate.format_sql" value="true"/>
        </map>
    </property>
</bean>
